Photosensitizer APDT parameter Activity of microbe Reference Nitrogen-doped graphene quantum dots 0.1 W/cm2, 670 nm E. coli was eliminated nearly 100% after 3 min laser irradiation exposure. [19] Fullerene monoadducts White light: 150 mW/cm2; UV light: 30 mW/cm2 When excited by UVA light or white light,fullerene monoadducts can kill three different classes of pathogenic microbial cells, such as MRSA, E.coli, and fungal yeast C. albicans. [20] Black phosphorus nanosheets Xenon lamp: 200 W, 1 m high Black phosphorus nanosheets can kill 98.90% and 99.51% E.coli within 10 min. [21] Chitosan-assisted MoS2 nanosheets as coating in titanium implants 660 nm, 0.5 W/cm2 When irradiated by only 660 nm visible light for 10 min, the nanosheets exhibit antibacterial efficacy of 91.58% and 92.52% against E.coli and S.aureus, respectively.
